Electric Vehicles: The Significance of Body in White (BiW) Technologies

 Electric Vehicles: Body in White

In the realm of electric vehicles (EVs), the Body in White (BiW) refers to the stage of automotive manufacturing where the car body's sheet metal components have been welded together but before moving components, electronics, and trims are added. This phase is crucial as it lays the foundation for the vehicle's structural integrity and safety.

As the automotive industry shifts towards electric vehicles, the BiW needs to adapt to accommodate the specific requirements of EVs, including battery housing and weight distribution. This evolution has prompted innovations in fastening technology to ensure that these vehicles are not only safer but also more reliable over their lifespan.

One significant advancement in BiW for EVs is the use of high-strength and corrosion-resistant materials in fasteners. These materials help withstand the stresses and strains that EVs experience, thus enhancing the overall safety standards. Key fastening solutions employed in innovative BiW designs include welding studs, self-piercing technology with flow drill screws, and structural blind rivets. Each of these options provides robust joining capabilities while facilitating ease of assembly and disassembly, crucial for efficient EV production and maintenance.

Welding studs, for instance, offer a no-hole solution that doesn't compromise the substrate’s integrity, making them ideal for maintaining the strength of the vehicle's frame. Flow drill screws, on the other hand, combine drilling and threading in one step, significantly speeding up the assembly process while ensuring high vibration resistance—a critical factor for EVs.

Moreover, techniques like large-diameter clinching are utilized to avoid thermal stresses and reduce environmental impact during assembly. This method not only strengthens the thread but also improves the vehicle's overall ecological footprint by producing cleaner assembly environments.

As we move forward, the role of sophisticated BiW technologies in manufacturing electric vehicles cannot be overstated. They not only support the structural needs of EVs but also contribute to advancements in automotive design and sustainability, ultimately enhancing consumer safety and satisfaction.

7 criteria to prevent material fatigue

Image
Material fatigue is defined as an accumulating degradation of material caused by dynamic stress with amplitude below the tensile strength limit. From the practical perspective we can divide the fatigue into two groups:  low-cycle fatigue with number of cycles up to 104 and amplitude of stress above the yield point, where plastic deformation predominates  high-cycle fatigue with number of cycles more than 104 and amplitude of stress, usually way below the yield point, where elastic deformation predominates Low-cycle fatigue is not important for a design of the joint. During the low-cycle fatigue process, stress amplitudes usually exceed the yield point. Fasteners shouldn´t even reach this value of stress. On the other hand, we should be aware of the high-cycle fatigue! Designers of a fastened joint should always consider the influence of high-cycle fatigue when dynamic forces are expected!  On the figure typical example of dynamic loading cycle can be seen. The most important variab
